Looking for schematic for a decent full size amp.

Hey, im looking to start building a full size amp, but I'm unsure of which IC to base it on. Any suggestions/schematics you guys have would be really helpful.

LM3875 BPA.
Very full sized for Chip amp.

Thanks alot, I'll check it out and see if I can find some more info and specs.

Try LM3886 or LM4780 too.

Any of the National Chips are good. I think the LM4780 is already 2 channels and also has a PCB layout in the datasheet.

Can't get easier

It might be less work to use two lm3886 instead of one lm4780. The pin and the space needed for external parts wont be as tight.

This site has inverted schematics. It should be helpful.
